Installing magnetic contactor on input side of inverter

From the connection diagram, it seemed that not installing the magnetic contactor on the input side of the inverter is the standard for up to the A200.
Installing it seemed to be the standard from the A500.
Should I provide inverter protection?
Is it bad just to turn OFF the operation signal in response to an inverter alarm?

Answer

Basically, there is no difference between the A200 and A500.
For safer use, from the A500, it is recommended to completely shut off the power supply by turning OFF the magnetic contactor upon an inverter fault to protect the inverter.
